Actually, you even havent clear what do you doing, for me its really confusing how to find apropriate NOC for you. How many years of work experience do you have? and what title your contract, salary slips or etc says??
Have to tried CIC eligible tool and HRSDC website for have a idea about what category you fall in? If not then go through CIC eligibility tool here
http://www.cic.gc.ca/english/immigrate/skilled/tool/tool_01.aspand for HRSDC website, ... finidng right NOC code, go here and write in box your occupation, it will bring one list of NOC codes, then check one by one for make sure which NOC is representing your occupation and duties.
